Abstract: This invention relates to assays for a Plasmodium analyte in a liquid sample such as a body fluid. More particularly, the invention relates to a method and apparatus for the detection of a ligand in a body fluid such as urine or blood, which can diagnose malarial infection.

Abstract: A folding box blank (1) having a plurality of base portions (2, 3, 30, 31, 32, 33) and at least four side wall portions (10, 11, 14, 15, 16, 17) hinged thereon, wherein the in each case two base portions are arranged symmetrically with respect to one another.

Abstract: A system for controlling the pumping capacity of a lubricant pump for an internal-combustion engine, having a vane cell pump (2) which has a rotor body (4), rotor blades (10) which can be radially displaced in the rotor body as well as a lifting ring (12) (stator) whose position can be adjusted with respect to the axis of rotation of the rotor for changing the delivery volume as a function of operating parameters of the internal-combustion engine. The lifting ring (12) is linked to an adjusting piston (28) guided in a valve bore (30) of a pressure regulating valve (26), which adjusting piston (28) is acted upon by engine oil pressure on a piston front side (34), the piston front side (34) being connected with the piston rear side (37) by way of a throttle bore (62).

Abstract: Mass spectrometric techniques are provided for detecting the presence of parasites that accumulate unbound heme in red blood cells (including malaria parasites), based on the discovery that unbound heme can be detected and quantified using mass spectrometry. In one aspect of the invention, the method includes the steps of: obtaining a blood sample from the animal; preparing a test sample on a support from the blood sample, and inserting the support into a mass spectrometer for analysis. Next one obtains a mass spectrum of the test sample and determines whether the mass spectrum contains a mass/charge signature of unbound heme. If it is determined that the mass spectrum of the test sample shows the mass/charge signature of unbound heme, the animal is diagnosed as infected with malaria parasites.

Abstract: A method and apparatus for particle collection (30) that is characterized by co-aerosolizing fluids (62) into an air stream (34) containing the particles to be analyzed to significantly enhance their collection and identification efficiency is provided.

Abstract: Techniques to modify and apply aerogel coatings are described, including the application of spray-coated aerogels. The approach eliminates several of the wet chemical techniques previously needed for processes such as MALDI processing, and simplifies the automation of processes such as continuous monitoring in a sensor based format. With respect to MALDI processing, the preferred embodiment uses an acid-doped silica aerogel coated tape as the collection media as well as the matrix support. Although aerogels are disclosed as a preferred matrix material, other materials may alternatively be used, including linoleic acids, oleic acids, PEG (polyelthylene glycol), preferably in tape format.
